Zdravim,
mate stim nekdo zkusenost ? Chtel bych experimentovat a zkusit nahradit svuj 133 km spoj za tyhle jednotky. Myslite ze od toho muzu cekat vic nez soucastny stav ?

Tj. 2x RB912 s rocket dishem 34 dB a vysledkem 50/50 full duplex 80-100 half duplex ?

Spoj 133 km v 5GHz? V Česku? To jako fakt?
Nicméně plno informací a zkušeností z instalací najdeš tady:

Pominu li fakt, ze to v normach nedas, tak me opravdu zajima, jestli to spojis a jak to pojede

Proc bych to nespojil ? Kdyz ted ten spoj funguje ? Je to sice jen testovaci hracka, ale funguje.

Umí tato jednotka regulaci do mínusu? pokud ano tak by to v normách dal se 120cm ant

a kde koupim 120 cm antenu ? : )

v polsku a nebo se zeptej u tyhana či štourače

Oslovil jsem je. A kde v Polsku mas nejaky zdroj ? Docela bych to chtel zkusit.

bohužle si ten šop přesně nepamatuji ale měli tam fakt mraky antén, z čech to snad bude určitě dělat alcoma, ale nevím jak by si to tam napojil. největší co se masivně dělá je ta ubnt 34dB tedy 1m a kus centrimetrů

Ahoj,

ano umí do -10 a dokonce to i funguje

Zdravím, má už někdo nasazeno? Jak velké jsou zde problémy s DFS? Stejné jako u AF 5?

HI! This is my first post on your forum and due to fact I cannot write in Czech (but i can hardly read) I would answer about it in English We have Jirous 29 DuplEX antennas (regular MIMO 2x2) with AirFiber 5X on 40km link. Signals are high around -62dBm which is enough to establish stable link with 64QAM modulation which can easily push around 120Mbit in one direction (depend of course on TX duty selection) in 20MHZ channel. Pushing AF5X to 133km link I think is useless - it will be hard to establish stable 16QAM modulation, so question is how much of traffic you need in real enviroment? Or it's even worth to build such link. Sometimes is better to buy a fiber transit to such location or closer location and make shorter link with high rates.

Hello mate,
i have more than 6 months to this poitn ( 133 km ), RB 912 with RocketDish 34 dBm, i have signal around -58 dB ( when i ignore RIP limits ) and i can push around 80-100 Mbitu on 1 TCP TX or RX. When i try 1 TCP on both TX + RX its around 45-50 Mbitu full duplex . Its my skill with this long point. I only thing, if with AF-5X is possible tak more than this results . Its only for tests and 4fun at this moment.

Great! If you have such link with Mikrotik I assume that AirFiber 5X will handle much more than Mikrotik due to fact AirFiber is much more effective per Hz. With signals above -60dBm you can get 256QAM modulation easily with resonable TX output ~19dBm. Look into papers : http://community.ubnt.com/t5/airFiber/A ... 1#U1322241

In Czech Republic exist local limitation in EIRP limit rule. It says max. 30dBm EIRP on 5GHz band. It means antenna gain + TX power in dBm. Specified distances btw points of the radio link are too far for legal usage. Thats the fact. No negotiations about AF5X max parameters.
